I started the reading. I need some refreshing about the math of this chapter: It was not very clear to me why it was demonstrated the calculation of A, and how do we calculate V and Ω. The fact that PX is whitened, if X is, is clear. :)

I liked that the Crammer-Rao is included. Again, some math here need some more exploration to crystal clear them in my head. But the big picture is understandable.

Also about empirical risk, I think that instead of argmax we should say argmin, because we want to minimize the cost function.

I liked a lot the link between categorical cross entropy and KL divergence. I didn't know that it is based on that.

Thanks Antonis. Unfortunately, in this period, I can't follow the chat very frequently. However, yes, argmax is a typo :)
